I also was informed by the sales rep at the store that I qualified for $200 trade in on my spotless iPhone4. Went to the site www.trade-in.vzw.com/ and filled out the info, clicked "Submit" a popup sad "Successfully submitted" or some such.

Never heard another word. Called today to follow up and was told my submission was never received. Now if I go back to the site and do the appraisal, it says I might $29.
Looks like I was far from the only one taken in this scam and near as I can see from responses on this blog, no one has received any satisfaction from Verizon.
